ATTORNEY Patented Sept. 8, 1931 UNITED STATES JOSEPH H. LANCOR, OF CRANSTON, RHODE ISLAND CLASP Application filed May 14, 1931. Serial No. 537,276.

My invention relates to clasps for articles of personal adornment, and has for its essential objects to facilitate the disengagement of the clasp when desired; to effect this end by Q a positively acting means; to provide a disengaging means that is accessible and operable by an easy natural movement; and to attain these ends in a simple and inexpensive structure.

19 To the above ends essentially my invention consists in such parts and in such combinations of parts as fall within the scope of the appended claims.

In the accompanying drawings which form 15, a part of this specification,

Figures 1 and 2 are a front elevation and side elevation. respectively of a clasp embodying my invention in closed or engaged position,

Figure 3, a central longitudinal section of the same in open position,

Figure 4, a section taken on line 14 of Figure 2,

Figure 5, a fragmentary section taken on 25 line 5-5 of Figure 1,

Figure 6, an isometric view of the disengaging member,

Figures 7 and 8, side elevations of modified forms of my invention, and

Figure 9, a transverse section taken on line 9-9 of Figure 8. 1

Like reference characters indicate like parts throughout the views. 1

My clasp is bent up from a strip of thin resilient sheet metal and comprises an oblong front plate 11 integral with one of whose ends is a slightly curved resilient lip 12 provided with a horizontal slot 13 in its forward portion. Integral with the other end of the plate is a rearwardly directed loop 14 continuous with a resilient arm 15 provided with an intermediate bend 16 and terminating in a loop 17.

Slidable and tiltable in the slot 13 is a de- 45 taching member 19 cut and bent up from a thin sheet of metal comprising a straight shank or body 20 extending loosely through the slot, a rearwardly directed hook 21 upon its outer end, and a rearwardly directed hook shaped triangular cam 22 upon its inner end.

hen the clasp is in normal or closed position the member 19 is horizontally disposed, as shown in Figure 5, with the tip of the cam 22 resting against the loop 17, and the face of the shank 20 in contact with the upper Wall of the slot '13. By the inward pressure of the member 19 by the operators finger against the hook 21, the cam forces the loop 17 rearwardly and thus disengages the latter from the yielding lip 12, and the resilient arm 15 assists in detaching the parts. As the transverse dimension of the slot is sufliciently ample the operator may if necessary or convenient tilt the outer end of the member 19 rearwardly, and thus supplement the cam action by a lever action by tilting movement.

The clasp and parts shown in Figures 1 to 6 inclusive is best suited for use as a lingerie clasp.

In Figure 7 the front plate 25 is straight rather than curved and has fixed to its face a settingrbase 27 for ornaments 28, and this form of clasp is preferred for use in the hair.

In Figures 8 and 9 the front plate 30 has lateral slotted extensions 32. One extension receives the terminal loop 34 of a pivoted band 35, and the other receives the terminal attachingfinger 36. My clasp in this form constitutes a bow holder. I

I claim i 1. In a clasp, an oblong plate, a curved lip upon one end of the plate provided with a slot in its rear portion, aresilient arm integral with the otherend' of the plate, a loop upon the free end of the arm adapted to be overlapped by the lip adjacent the slot and a detaching member loose in the slot and engageable with the loop.

2. In a clasp, an oblong plate, a curved lip upon one end of the plate provided With a slot, a resilient arm integral with the other end of the plate, a terminal loopupon the arm slidably engaging the lip, and a detaching member including a shank loose in the slot, and a terminal cam engageable with the loop. 1

3. In a clasp, an oblong plate, a resilient arm integral with one end of the plate, a loop upon the free end of theplate, a lip upon the other end of the .plate overlapping W1 the loop an (1 provided with a horizontal slot, and a detaching member comprising a shank loose in the slot, a hook upon the outer end of the shank, and a cam upon the inner end 5 of the shank normally engaging the loop.

In testimony whereof I have affixecl my signature.

- JOSEPH H. LANOOR.
